I was talking about swapping animations, all that takes is some renaming and replacing. You don't need to open the files

If you really want to help out just download zmodeler (which you can get for free, ask edsir or coremax they once passed me a link when my zmodeler stopped working).

Then just follow coltmaster's tutorial (it's somewhere on gta4-mods.com)

I have the zmodeler (in version 2.1.1, which supports GTA IV exporting, in this case, the .wdr), but it's useless because it's in unregistered version. If I have to get it full working (like importing objects and things like that), I need to register, and that wastes my dad's money just to buy zmodeler. Indonesia now raises the fuel price a few days back, and my economy isn't very good at all.
Any idea how?

Note that I'm not asking pirated files or whatsoever. I had a rule broken once, and I promise not to eat shit again.

EDIT: I've placed an attachment picture showing why the zmodeler is useless. I'm trying to import a .wft file and this shows up: "Only registered version can import files."

If you aren't familiar with it, the Buffalo Rifle is the most powerful gun in Red Dead Redemption. It can hold on one round only, but that alone could kill a man. It is based on the real life 'Sharps Rifle'.

I searched the internet for the mod, but I couldn't find one - so this is where I request it!

To make the mod realistic, I think you could include some of these features:

Find me a 3d model I can work with and I'll consider making it (a .obj model). I can't seem to find it anywhere, not on red dead's name and not on the original name.

The only other way would be creating it from scratch, something I'm not experienced in and which would take ages. So I guess you'll have to find some similar gun that you can find a 3d model of, or just leave it at this.

The GRIM's Weapon Pack have a G3SG1, but I bet there's something better than that. Idk where I can search it on gamebanana, but I have a picture in an attachment. It's a G3SG1 on Counter-Strike. Looks good in quality.

Yeah, I already enjoyed it since idk how to mod, but I mean without any custom attachments, just a scope like PSG-1 and folded bipods , similar like GRIM's G3SG1. Idk where I can search it on gamebanana.
